James D. Hutton

He is assumed to have joined his brother and uncle on many of their travels around California in the late 1840s; a number of his sketches survive from this period.

[2][3][4] On April 22, 1859, James Hutton was appointed as topographer at a salary of $120 a month with the Raynolds Expedition led by Captain William F. Raynolds of the Army Corps of Topographical Engineers to explore the northern Rocky Mountains from Fort Pierre in the soon-to-be Dakota Territory to the headwaters of the Yellowstone River.

Hutton and Recontre became the first caucasians to reach the rock formation, later known as Devils Tower; Raynolds never elaborated on this event in great detail, mentioning it only in passing.

[11] Hutton joined the Confederacy early in the war, delivering the Federal plans for the defense of Alexandria, Virginia to the South.

[8] The Manuscripts Department of the Huntington Library and Art Gallery houses a collection of sixteen of James D. Hutton's drawings.
